1. I went to the internet to find the service manual for the Maytag microwave.2. I opened up the oven and started measuring the resistance of the diode, capacitor, transformer, and magnetron between terminals and then to ground. The transformer and magnetron were well within the resistance limits. The diode was shorted in both directions(+-). The capacitor was fully open in both directions -- high resistance. 3. I ordered the 2 parts, installed them, and ran the oven. Worked perfect first time.4. Reinstalled oven and worked ever since (1 week so far).5. The secret was that the transformer had a load hum. I figured the transformer was OK. The magnetron had no short between filaments and ground to filaments. The only two left were the diode and capacitor. The first two are about $200 -- almost the value of a new microwave. The $70 repair was well worth it. If the first two were still bad, then tempted to buy a new oven.

Remove top grille (2 screws), undo control panel (1 screw). Tilt down control panel, switches are on the left. There are actually three switches that are involved with the door, two horizontally mounted, one vertically mounted. This would be an EASY REPAIR, but it took me a while to figure out which of the three switches was bad, and also took a while to figure out that there is a plastic rod that inserts through the hole in the switch body. Once i figured this out went like a breeze. Lower horizontal switch was the bad one, but since the kit came with two switches i went ahead and replaced the upper horizontal one as well. IT appears that the horizontal switches are probably more likely to fail than the vertical switch based on the position of the switch and force angles. Works great now!

loud buzzing noise

The repair went well...I am so glad that I read this info before buying a new microwave....it saved me lots of money. I did have a repair man come and look at it and he told me to buy a new one but it cost alot of money when it wasn't necessary. I did the repair and I was very proud of myself.Three men watched a woman fix this and it was no problem...they were impressed also....

The lamp burns out occasionally

Once I got the replacement bulb, the repair waseasy. I needed to unscrew one side of the lamp assembly and pop the new bul in.

My problem was getting the right light. The local hardware store didn't carry quite the right halogen lamp and the one I bought burned out the wires that hold the light. THis was a costly repair --- about $100. So I was delighted when Part Select had the lamp I needed. They were prompt in sending it out and I was very satisfied.

Close the door on the microwave, punch in the # nothing happened

I removed the unit from the wall. Took the cover off. Set the unit on its side. It revealed the working parts. Removed the old micro switches. Put in the new oness. Presto, it worked. Very easy for me.The parts was delivered almost before my notice they were shipped.

Broken Stainless Steel Microwave Molding

We just bought a house where the top piece over the microwave door was missing. It had plastic tabs that were supposed to hold it on, broken off, so this piece had to be replaced. It was held in place by just 2 screws, so even I could fit the new piece on in about 3 minutes. I feel so proud of myself!

Fan motor and magnetron did not come on, but every thing else did.

Problem would come and go. Found service schematic inside unit. Perform all the suggested tests. One possible solution was the primary interlock switch shown on the schematic and a check found the switch stuck. It would free up some times but would stick again in the open position. Ordered switch which was a simple plug in unit.

1. Removed cabinet screws (10-15?). 2. Removed cabinet. 3. Removed top interlock switch which actually was not defective. The press clip connection appeared as if it had been arcing for quite some time and the corrosion created resistance sufficient to prevent the current from getting through the switch. 4. Replaced switch anyway but broke plastic retaining clip despite every effort not to do so. Reset broken clip with super glue. 5. Reassembled cabinet and appliance is in good working condition.

Our maytag microwaive sounded like a thrashing machine when running!

Over a period of a year or so, our over the stove microwaive oven started sounding like a thrashing machine every time we turned it on and got progressivly worse. The repair service wanted nearly half the cost of the appliance to just come out to take a look. I removed the oven from the wall cabinet, removed the cover and discovered that the cooling fan blade had come loose from the motor shaft and was hitting the casing. I ordered the fan motor assembly from you folks, replaced the faulty fan, and the problem was resolved at about one half of the cost of a service call.

Fan come loose on motor shaft

Repair was very simple, removed microwave from wall and removed top cover and found fan loose on shaft. Removed fan and motor, new motor and fan slotted, good upgrade. Installed new motor and fan and top cover on, installed back on wall plate, tried and wife said it sounds like a new one.
